\subsection{Scenario 8.10 Interest}

This scenario is about the yearly payment of interests on saving accounts. SAB pays out interests to its customers on the first of January. The calculation and payment of these interests is illustrated in figure \ref{fig:seq_8_10_Interest} on page \pageref{fig:seq_8_10_Interest}. Each interest is executed as a separate transaction. These Transactions are executed by the \emph{Transaction Processing System} as illustrated in detail in figure \ref{fig:seq_UC11_Execute_transaction} on page \pageref{fig:seq_UC11_Execute_transaction}. For each executed interest Transaction a notification will be sent to the corresponding customer's \emph{Notification Inbox}.

The use cases touched in this scenario are:
\begin{itemize}
 \item UC21: Pay interests
 \item UC11: Execute transaction
\end{itemize}
